METHOD OF MIXING ALLOYS.

SPECIFICATION forming part of Letters 'Patent No. 487,338, datedDecember 6, 1892.

Application filed August 18,1892. Serial No. 443,419. (No specimens.)

To all whom it may concern:

Be it known that I, WILLIAM R. THOMAS, a citizen of the United States,residing at Catasauqua, in the county of Lehigh and State ofPennsylvania, have invented certain new and useful Improvements inMethods of Mixing Alloys; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My present invention or discovery relates to the art of working metals,and has for its object certain improvements in the method or process ofmixing alloys, whereby their density is increased and the grain of themetal rendered more regular than under the prevailing practice of mixingalloys.

The invention or discovery will be fully disclosed in the followingspecification and claims.

In the accompanying drawings, which form part of this specification andare used for the purpose of illustration, Figure l represents a verticalsection of a vessel and an agitator used for the purpose of carrying outor practicing my method, and Fig. 2 represents a plan of the agitatordetached or separated from the vessel.

Reference being had to the drawings, Aindicates a vessel, which may be aplain cylindrical iron vessel ora crucible or a ladle, and B anagitator, which consists of a disk provided with numerous perforations aand a handle b, by which the agitator is reciprocated vertically tobreak the molten metal into fine streams to insure thorough mixing. Thevessel may be provided with a porter-bar C for handling it, if desired.

The mode of procedure under my process is as follows: The alloys aremelted in one vessel-such asacrucibleorladle-and poured into anothervessel, as A, heated to maintain .the heat of the molten alloys, andupon the up the body of met-al until thoroughly mixed. After the mixinghas been completed the metal is poured into suitable molds in the usualway of casting.

For mixing metal-s requiring phosphorus, phosphide tin is first made by'placing stick prosphorus in the bottom of the vessel A under the disk Band molten tin poured on the perforated disk, and after the reactionceases the disk is reciprocated until the metals have been thoroughlymixed. After the phosphide has cooled a required amount necessary forthe purpose it is placed in the vessel A, properly heated, and under thedisk B and from the crucible the molten metal is poured upon the diskand the phosphide, and when reaction ceases the metal is agitated andbroken or divided into numerous streams by reciprocating the disk Buntil a thorough mixture of the metal has been secured, when the mixedmetal is poured into molds.

By the foregoing operation the metals are so thoroughly mixed as to forma homogeneous body, which when broken shows no evidence of separation,is of increased density, and the grain of the metal is far more regularthan when mixed in the usual way by stirring.

In practicing this process it has been ascertained that the density ofan ingot of given dimensions is increased more than ten per cent.

Having thus fully described my invention, what I claim isl. The methodof mixing alloys, which consists in pouring the molten metals into avessel and subsequently breaking or dividing the mixture into numerousstreams in said vessel.

2. The method of mixing alloys, which consists in breaking or dividingthe molten metalsinto numerous streams while pouring them into a vesseland subsequently further breaking or dividing the mixture into numerousstreams.

In testimony whereof I affix my signature in presence of two witnesses.
